Gravity Powered LED Lamp Invented

This gravity powered lamp generates as much light as a 40 Watt bulb.

Clay Moulton of Springfield, Va., who received his Master of Science in Architecture with a concentration in industrial design from the College of Architecture and Urban Studies in 2007, created the lamp as a part of this master’s thesis. The LED lamp, named Gravia, has just won second place in the Greener Gadgets Design Competition as part of the Greener Gadgets Conference in New York City.

Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated.

The electricity is generated by the slow fall of a mass whose torque harmonic drive gear head that spins a set of 12 high-strength neodymium magnets that constitute the rotor. The rotor spins within a stator housed in the base.The resulting elecetricity is rectified and powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light source.

The operation is silent and the housing is elegant and cord free — completely independent of electrical infrastructure.
